Did Dave sneak this one in under our keyboard keys or am I just getting around to discovering it? With v18, I found that the linetype spacing can be adjusted with a symbol in its unexploded condition. I have some electrical symbols that were unexploded and that had dashed lines that I use for demo work. I noticed that the dashed line spacing had gotten very tight when I looked at them in the drawing. But, when I pulled up those symbols from the browser, they contained the correct, longer dashed line spacing.

I found that the symbols in the drawing can change line spacing, without exploding them, by changing the line spacing to 1'-0". Very cool little trick to be able to change unexploded symbols in a drawing and without having to explode them.
